How to Convert Sony MMV file to MP4 AVI WMV on PC and Mac

I want to share my experience of converting the Sony MMV file to MP4 or any other video formats like AVI WMV because I know how hard it is to get videos off the Sony camera and onto the computer and convert.

MMV Video file, with the suffix .mmv, is created by some Sony digital camcorders by 12 Mbit/s MPEG-2 compression. I thought it could be easy to convert MMV since it is in MPEG-2 but I have tried a couple of video converters hoping they can read the Sony MMV format. However, when I drag a .mmv file into the apps they do not accept it. I finally worked it out and will show you how to convert Sony MMV to MP4 AVI WMV.

Sony discontinued the use of MicroMV camcorder models in 2006. So we know MMV won’t be our big trouble, but just in case, this guide will be of help.

Sony MMV File Converter for PC/Mac

What I recommend is an all-in-one video converter, video editor, online video (YouTube) downloader, DVD/Bluray burner. It is an all-purpose video toolbox for you: Wondershare UniConverter.

When it comes to video converting, Wondershare is always my top choice as it supports almost all video formats and converts between them. And I think it is the best Russia World Cup video converter no matter which Camera you use to record your splendid moments during the 2018 World Cup. We are also able to custom each profile and save as our own. The high-speed conversion mode impress me a lot, making Wondershare Video Converter the fastest video converter!

How to Convert Sony MMV to MP4 AVI WMV

Converting videos with Wondershare is always easy but converting MMV file gives us a little trouble, but no worry, I will walk you through.

Step 1. Download and Install

Follow the above download links and free download Wondershare MMV file converter. Install and launch it.


It’s NOT possible to drag and drop MMV directly to Wondershare UniConverter and MMV file is grey out when we try to add through the “Add Files” button. We have to rename or change the file extension MMV to MP4 or any other video formats that Wondershare supports, including AVI, MKV, WMV, SWF, M4V, etc. Then we can easily add the renamed file to Wondershare by drag-and-drop or “Add Files”:

Step 3. Convert MMV to MP4 AVI WMV

If you want to convert MMV to MP4 after it is loaded, you can go directly for the Convert All button as MP4 comes as the default output format in Wondershare with original resolution in H.264. 

Tips for Converting MMV

Below are some of my tips for converting MMV:

1. If you want to convert MMV to AVI, WMV or any other videos formats, click the drop-down menu of “Convert all tasks to” and the Editing button to custom your own profile.

2. High-Speed Conversion is NOT available for MMV as it only supports H.264 in MKV, AVI, MPG, TS, TRP, MP4, M4V, M2TS, MTS, MOV, FLV. For more details, please visit this page. But it is always recommended to Turn On. The converting speed would be super fast.

Thanks! This was very helpful and works well. One question though. When I convert to mp4, same as source, original resolution, the file is 1/4 the size of the original and when I play both on VLC, the original is better quality. How do I prevent this loss of quality?

Would love your thoughts, please comment.x
